 * Class FeaturePolicy is a simple helper which allows applications to

 * from the same domain and full screen as well from the same domain.
 *
 * Even if a value gets modified above defaults will still get appended. Please
 * notice that Nextcloud ships already with sensible defaults and those policies
 * should require no modification at all for most use-cases.
